Title: Power station heat exchanger - has enlarged water chamber containing preliminary cleaning and cleaning ball-separation sieves
Inventor: NEUHAEUSER DIETER ING GRAD
IPC: F28G1/12
Filed: 1979-10-20
Abstract: The power-station heat exchanger is particularly in the form of a condenser, having a oreliminary cleaning sieve for the cooling water, together with pipe-cleaning equipment. It incorporates pipes and water chambers, while the cleaning equipment incorporates separation sieves for the cleaning balls, and a return pipe with pump and sluice valve for the latter. One at least of the water chambers (5,6) is enlarged, and contains the preliminary cleaning (2) and/or the separation (8) sieves. The pipes can merely form a path for the water between upstream and downstream chambers, the downstream one (6) containing the separation sieves and the upstream one the cylindrical preliminary cleaning sieve. The cooling water enters the latter from the outside, while the ball return pipe (9) discharges into its cylindrical interior (15).

Title: Electric servo drive for motor vehicle windscreen wiper - has slide contact which provides contact point for signalling and switching and coping with wear
Inventor: PROHASKA HANS
IPC: B60S1/08
Filed: 1980-06-14
Abstract: The drive has at least one slide spring, carrying a slide contact, which abuts a contact path for signal and/or switching triggering. The drive has a setting element for a relative movement between the contact path and the slide contact. The latter is shaped so that during effective operation and wear it retains a firm position on the contact path. Pref. the contact path is provided on a switching disc (16) driven by an electric motor (13). Together with the slide contact it forms a part of a position switch for the control of the electric motor, or another electric unit. It has a conductive path (17), at least partly lying in the contact path. The slide contact travels both over electrically conductive and non-conductive sections (19,20). The slide contact may be larger in the direction transverse to the relative movement along the contact path than in the contact direction.

The neck chambers can be separated from the body ones, and there can be detachable pillow (3) and leg cushion (2) sections.
Patent DE-3026562-A1 (DE)
Title: Line connection cradle switch on telephone subscriber's appts. - has defined contact travel time set by spring and bar to prevent incorrect operation
Inventor: RUZIC HUGO ING GRAD
IPC: H04M1/08
Filed: 1980-07-12
Abstract: The telephone cradle switch ensures that the switching action is independent of the speed at which the handset is lifted or replaced. The operating bar (3) for moving the spring-loaded and biased switch contacts (4) has two flanges (6,7). The forked end (2) of the cranked lever (1) attached to the cradle operates between these flanges (6,7). The switch position only changes when the fork (2) bears against one flange or the other with sufficient pressure to overcome the bias of the contact springs (4). At this point the switch changes state inside a defined time, approximately 5 milliseconds. With the proposed modification a very flow movement of the operating lever (1) is much less likely to cause switching delays between individual contacts than was the case with earlier designs having only one flange (6).

Inventor: APFELBAUM HELMUT
IPC: C02F1/04
Filed: 1980-08-04
Abstract: The purification method of polluted water by dissolved materials which are separable through crystallization, consists in circulating the solution in a heat exchanger where the vaporization temperature is reached, in feeding the solution into a separator in which the vaporization is achieved by expansion. The solution is then fed back to the heat exchanger and the solid materials precipitated by the concentration of the solution are withdrawn from the liquid flow. The apparatus for implementing the method comprises a heat exchanger (14), a separator (16) connected to the exchanger, an extraction device (42) and a means (48) for feeding back the solution to the exchanger.

Title: Manually operable pulse transmitter
Inventor: KNOETTNER ALFRED
IPC: G04C3/00
Filed: 1981-01-26
Abstract: A manually operable device for interrupting two different actuating circuits in a pulsed manner, especially for producing actuating pulses for electronic clocks, has a latching perforated disc (6). The latching perforated disc (6) can be caused to move in an axially oscillating manner by means of a latching disc (4) which is operated by hand. The latching perforated disc (6) can furthermore be driven within a rotation angle, which is bounded by two limit positions, in the rotation direction. A contact spring (12) which is supported in the perforated latching disc (6) interacts with one of two mating contact elements (13, 14) (which each belong to one of the actuating circuits) in each limit position of the perforated latching disc (6). The contact spring (12) interacts with the respectively associated mating contact element (13 or 14) in such a manner that the relevant actuating circuit is interrupted in time with the oscillating movement of the perforated latching disc (6). <IMAGE>

Title: Push-through lock for a two-wheeled vehicle
Inventor: JUNKER KARL-HEINZ
IPC: B62H5/14
Filed: 1981-01-29
Abstract: The push-through lock for a two-wheeled vehicle, according to Fig. 2, comprises a lock housing (1) which can be fastened to a frame part (4) and in which a latch pin (2) is guided and can be secured, and comprises a receiving housing (3) which can be fastened to the opposite frame part (5) and is intended for the free end of the latch pin (2). The lock housing (1) can be secured on a base plate of a standard spoke lock and the receiving housing (3) can be secured in the manner of a pipe-clamp connection by means of a holding clip. By this means, not only is a simple and cost-effective construction achieved which is highly effective in terms of the security which can be achieved, but also the advantage is achieved that the frame parts of a whole series of two-wheeled vehicles can be prefabricated without splitting them up, irrespective of whether they are to obtain a conventional spoke lock or a push-through lock. <IMAGE>

Abstract: The invention relates to a bench-mounted chain saw for cutting firewood, with special main safety features, the object being to design a compact tool for high performance, operating reliability and accident prevention. This object is achieved according to the invention in that the fixed saw bench (1), at bearing blocks (5), carries the bearing arrangement (2 and 4) for the saw-chain drive shaft (3), the latter being provided with a chain pinion (6) and having a common centre of rotation with a guide-bar holder (8, 9 and 10) which is pivotable and guides the saw guide bar (11) and is provided with a bow (12) spanning the saw guide bar (11) and having an operating handle (15). In the rest position, the saw guide bar (11) is located inside a guide-bar guard (19) on both sides, which is provided at its front side with claws (20), is pivotable like the saw guide bar (11) and is held by a spring (18). When the saw guide bar (11) is moved by means of the operating handle (15) up to the wood (22) to be cut, the electric motor cuts in and likewise cuts out again when the cutting operation is complete, the spring (16) pulling the entire saw unit back into the initial position. <IMAGE>

Title: Device for preventing shutter blades (leaves) from springing back
Inventor: SHIMADA FUMIO
IPC: G03B9/36
Filed: 1981-07-06
Abstract: A description is given of a device for preventing shutter blades or the shutter curtain from springing back. The device is constructed so as to provide a plate spring, which projects into the space where a shutter operating element moves, so that the movement of the shutter operating element is braked in its final phase by means of the plate spring. The shutter operating element is then retained by the plate spring in order to prevent springing back. At the same time, a switch of an electric circuit of the camera is actuated by a second plate spring.
